I wouldn't trust them completely...many growers tend to use them as a guideline rather than the law. Different rootstocks, scions and seasons give variations.
I haven't double-checked recently but I recall reading that the experimental results are based on 30 minutes at the temperature. So if it is 10% kill at 30 minutes, it might be worse if it stays at that temperature for several hours.
The good news is that it looks like we're about to have a week or more of sun and most of my trees haven't bloomed yet
